Writer Liz Smith revealed the union midway through a column in the Chicago Tribune. Smith was recapping her New Year's Eve celebrations and gave a shout out to her "longtime friends."

"Lily Tomlin and her love, the writer Jane Wagner, got married on the eve of 2014," wrote Smith, adding, "My wish is that their happiness will be as great as their combined talents."

Tomlin, 74, and Wagner, 78, met in 1971 while working on Tomlin's comedy album, "This Is a Recording." The album, Tomlin's first, went on to win the Grammy Award for Best Comedy Recording in 1972 and features the comic in character as Ernestine, the sharp-tongued telephone operator she made famous on the TV series "Laugh In."
